I'll start with Cooking Over Campfire Coals from 4-H Youth Development and Illinois State University. 7 pages of tips for equipment, how to start a fire, safety tips and more.
This list is various 1-10 page booklets and recipes for tin-foil dinners.
Tinfoil apples with cinnamon and tinfoil potatoes are good options for plant based meals while you're camping.
